>             Project: Xerces-C++
>          Issue Type: Bug
>          Components: Utilities
>    Affects Versions: 1.7.0

> Platform: PC

> I have several threads (CWinThread) that use Xerces. Sooner or later one 
> specific thread gets stuck in ThrowXML. The exact point varies depending on what 
> I send in systemID. This is one example:
> void XMLURL::setURL(const XMLCh* const    baseURL
>                   , const XMLCh* const    relativeURL)
> {
>     cleanup();
>     // Parse our URL string
>     parse(relativeURL);
> 	//
> 	//  If its relative and the base is non-null and non-empty, then
> 	//  parse the base URL string and conglomerate them.
> 	//
> 	if (isRelative() && baseURL)
> 	{
> 		if (*baseURL)
> 		{
> 			XMLURL basePart(baseURL);
> 			if (!conglomerateWithBase(basePart, false))
> 			{
> 				cleanup();
> ---->				ThrowXML(MalformedURLException, 
> XMLExcepts::URL_RelativeBaseURL);
> 			}
> 		}
> 	}
> }
> [ baseURL = "Client" relativeURL = "Information-1-0.dtd" ]
> The calltree proceeds with:
> MSVCRTD!__CxxThrowException@8
> KERNEL32!77e989d1()
> so there are no more clues there I guess. The CPU is at 0% and it appears as 
> though everything is stuck in some mutex.
> I've made a (large) test program that spawns 50 threads and parses 50 DTD'd XML 
> documents in each and it also occasionally gets stucks.
> Brief facts of the case are:
> * Single thread single point of initialization.
> * Uses SAX.
> * New parser, etc. for each document read.
> * Uses MemBufInputSource.
> * Uses MS VS6 sp5.
> Sorry if this provides little clue as to what goes on. Please contact me for 
> more specfic information, if needed.
